An assembly for a motor vehicle has an exhaust gas-carrying pipe in which an adjustable element is arranged to control an exhaust gas flow through the exhaust gas-carrying pipe. An actuator is used to adjust the adjustable element. The actuator is connected in a planar manner to a vehicle structure via a connecting surface.

A valve for regulating two gas flows, includes a housing, two channels arranged in the housing for conducting a respective gas, a first flap arranged in the first channel for opening and closing the first channel, said first flap being rotatably arranged on a shaft, an electric motor for actuating the shaft, a second flap for opening and closing the second channel, and a third channel into which the first and the second channel lead. A connecting element is arranged on the first flap, and the first flap is connected to the second flap.

An intake air control apparatus of an engine includes a housing having an intake air inflow passage for receiving external air, an exhaust gas inflow passage for receiving recirculated exhaust gas, and an intake air supply passage for supplying the external air from the intake air inflow passage or the exhaust gas from the exhaust gas inflow passage to the engine. A motor gear rotates together with an output shaft of the motor. A connection gear is engaged and rotates together with the motor gear. A recirculation gear is engaged and rotates together with the connection gear. A recirculation valve opens and closes the exhaust gas inflow passage since the recirculation valve rotates together with the recirculation gear. An intake air gear is engaged and rotates together with the connection gear. An intake air throttle valve opens and closes the intake air inflow passage.

A valve comprises a coupling device having a driven member bound to the drive shaft of a flap, a driving member bound to an output shaft of an actuator, and an elastic member. The driving member comprises attachments that hooks up the elastic member to the driving member in a temporary position in which the elastic member is elastically loaded. The driven member comprises at least one release member that at least partly releases the elastic member of the attachments when the coupling device is brought to an intermediate state or the elastic member, when the coupling device is in the intermediate state, may be at least partly released from the attachments. The elastic member once released, adopts a definitive use position under the effect of relaxation of the elastic load, the coupling device then adopting the operational state.

Embodiments of the present disclosure present a valve assembly that includes a valve body having a gas passage bore, a valving bore extending along a longitudinal axis and intersecting the gas passage bore, a first bearing surface concentric with the longitudinal axis and a radially spaced apart second bearing surface concentric with the longitudinal axis, wherein an interface of the gas passage bore and the valving bore defines a flow port radially intermediate the first bearing surface and the second bearing surface. The valve assembly further includes a shaft valve extending along the longitudinal axis and rotatably mounted in the valving bore.

A valve for an exhaust gas line of an internal combustion engine in which a closure body is arranged in a duct and is positioned in a recess of a shaft, the closure body being pivotable about a rotation axis of the shaft. The closure body has two sides and a circumferential surface arranged between the two sides. The circumferential surface has sections with different external dimensions. A first external dimension of the circumferential surface of the closure body in a first section is smaller than the smallest internal dimension between end regions of the recess of the shaft in which the closure body sits. A second external dimension of the circumferential surface in a second section is greater than the smallest internal dimension of the recess of the shaft. The circumferential surface contacts the shaft in each of the two end regions of the recess.
